Supreme PCBN Blanks For Cutting Tools
The standard shape of SUPREME PCBN Cutting Tool BlanksTM is round. Other shapes, such as rectangle, triangle, square, semi-circle and so on, can also be customized per customers' requirements. Supreme Superabrasives has various equipments such as laser cutting machines, wire cutting machines and various processing equipments to cut blanks, regardless of their thickness into special sizes and shapes per customers' requirements.
SUPREME PCBN Cutting Tool BlanksTM consist of fine CBN grains sintered under ultra-high pressure and ultra-high temperature. Combining the strengths of hardness, thermal stability, thermal conductivity, and strong impact resistance ability characteristic of CBN, they are ideal for cutting tools for the machining of ferrous metal and alloy, all with high productive efficiency, high machining precision, and good surface quality.
SUPREME CBN Cutting Tools Blanks are composed by BN and PCBN two series:
BN characteristics:
1.  Solid CBN
2.  Good wear resistance
3.  Two sides can be used as edges
4.  High thermal resistance
5.  Excellent fracture resistance
BN application:
1.  High Speed Turning and milling of gray
     cast iron
2.  Turning of chilled iron,nickel-based iron and
     ductile iron
PCBN characteristics:
1.  Good weld based in the composite
     CBN layer and tungsten carbide base.
2.  High abrasion resistance.
3.  Good transversal repture strength
     resistance.
4.  Good chemic stability.
5.  Uniform dimension precision.
6.  Good consistency of processing.
PCBN application:
1.  Turning of castiron.
2.  powdered metals.
3.  exotic materials and heat resistant alloys.
4.  High speed milling of gray castiron.
